PEN.

SPECIFICATION forming part of Letters Patent No. 237,184, dated February1, 1881.

Application filed December 1, 1880. (No model.) Patented in England July16, 1878.

To all whom it may concern:

Be it known that I, FRIEDRICH WILHELM HOLDT, a subject of the Emperor ofGermany, residing in the city of Berlin, Kingdom of Prussia, and Empireof Germany, have invented certain new and useful Improvements inMetallic Pens with Unequally Elastic N ibs, fully described andrepresented in the following specification and the accompanyingdrawings, forming a part of the same.

My invention consists in giving greater elasticity to one of the nibs ordivisions of a metallic pen than to the other. I may obtain this unequalelasticity by making a slit in the one nib or half of the pen divided bythe central slit, or I may apply a slit to both halves, these slitsbeing different in their form and effects, whereas ordinary pens haveonly the central slit; or, if with a slit in each half, these slits aresimilarly shaped, and therefore each half operates in the same way. Bygiving unequal elasticity to the two halves or nibs of the pen formed bythe central longitudinal slit I obtain great ease and flexibility of thepoint of the pen, permitting the hand to guide it with less fatigue, andmake finer up and heavier down strokes. Further, the pen will lastlonger. 1

The accompanying sheet of drawings shows four pens of various forms, butall embodying my invention.

Figure 1 shows a steelpen'with a slit in one half or division only; andFigs. 2, 3, and 4 show pens'with a slit in each half or nib.

In all the figures, slit, by which I give greater elasticity to onehalf, division, or nib of the pen than to the other;'and it will be seenthat where an ordinary slit, b, is used my slit or exceeds it in lengthfor this purpose. 40

I may make more than one slit in each half or nib of the pen, but theslits in each half will always differ in form and effect.

Having now described and ascertained the nature of my said invention andin what manner the same is or may be performed, I desire it to bedistinctly understood that I do not limit myself to any particular formor dimension of slit, but that What I claim as secured to me by thehereinbefore in part recited Letters Patent, is-

A writing-pen one nib whereof is constructed so as to be more elasticthan its companion nib, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

FRIEDRICH WILHELM HOLD'I.
